Question

我遇到与Executing AWS CLI command from php results in Unable to locate credentials

完全相同的问题

我做了：

cd ~/.aws
mv config credentials

但它没有帮助。

所以我所做的是，配置和凭据都具有相同的内容：

[默认]

aws_access_key_id = AKIAJIPLT472C32RD6AQ

aws_secret_access_key = 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

output = json

region = ap-southeast-1

我在PHP文件中使用的代码是：

$s3 = system("aws s3 cp /var/www/html/v2/upload/__rmx4hqf.png s3://<bucket>/somefolder 2>&1");

Answer 1

我的猜测是php命令无法找到aws凭据文件，因为您运行的用户$ aws configure与php的有效用户不同。您没有提供有关如何运行configure命令或php脚本执行方式的足够信息，所以这只是我的猜测。

如果您通过环境变量AWS_CONFIG_FILE明确传递凭证文件的路径会发生什么？（例如$s3 = system("AWS_CONFIG_FILE=/path/to/credential aws s3 cp ...）？

Answer 2

尝试添加您的区域

$s3 = system("aws s3 cp /var/www/html/v2/upload/__rmx4hqf.png s3://<bucket>/somefolder 2>&1 --region ap-southeast-1");

像quiver一样，apache2从不同的用户运行，然后终止用户您可以使用命令

// inclusion of libraries
#include <stdio.h>
#include <stdlib.h>
#include <string.h>

/*
 Reads a string allocated by the stream.
 It stops at newline, not included in string.
 Returns NULL to EOF
 */
char *my_getline(FILE *stream) { // statement of function
    char *line = NULL; // this is just the pointer initialization
    size_t pos = 0; // definition of position variables and init
    int c; // a variable to store the temporary character
    while ((c = getc(stream)) != EOF) // read every character until the end of the file
    {
        char *newp = realloc(line, pos + 2); // To dynamically allocate memory, with reference to the number of characters and more '2' is only to compensate for the null character and the character (since it is 0)
        if (newp == NULL) { // checks whether memory has been properly associated or not.
            free(line); // if the line is not free the blank
            return NULL; // interrupts the program and returns NULL
        }
        line = newp; // if memory is allocated correctly stores the memory allocated to the line pointer
        if (c == '\n') // if a new line is detected
            break; // interrupts the while cycle
        line[pos++] = (char)c; // stores the character in dynamic memory and the new character in the new location.
    }
    if (line) { // if the line contains something then a null character is added at the end to complete that string.
        line[pos] = '\0';
    }
    return line; // returns the contents of the line.
}

int main(void) { // main statement
    char *str, *sub; // character punctuation statement
    size_t len1, len2, i, count = 0; // unsigned value statement "size_t is equal to unsigned int" so may also be <0
    int pos[count]; // declare a count array to insert the index then print it in reverse
    int j;

    // Here is the main string
    printf("Enter Main String: \n"); // print the entry and enter the main string
    str = my_getline(stdin); // inserts the entered string inside the pointer using my_getline function and using getchar analogue stdin to make the entered characters input from the standard input

    // here is the substring to look for
    printf("Enter substring to search: \ n"); // print the entry and enter the main substring
    sub = my_getline(stdin); // inserts the entered string inside the pointer using my_getline function and using getchar analogue stdin to make the entered characters input from the standard input

    if (str && sub) { // if string and substring && = and
        len1 = strlen(str); // inserts the string length in the len1 variable
        len2 = strlen(sub); // inserts the length of the string in the len2 variable
        for (i = 0; i + len2 <= len1; i++) { // loop for with the control that the substring is less than or equal to the main string ie len2 <= len1
            if (! memcmp(str + i, sub, len2)) { // here uses the memcmp function to compare the string and substring byte bytes
                count++; // count variable that is incremented each time the sub is found in p
                // here is where it gets in output
                // If the substring was found mold the index with the locations it was found
                pos[count] = i + 1;
                printf( "%d\n", pos[count]);
            }
        }
        // print to get reverse output
        printf("number of times%d", count);

        // print to get reverse output
        printf("%d", count);
        for (j = count - 1; j >= 0; j--)
            printf("%d", pos[j]);
 
        if (count == 0) { // if count is = 0 ie the substring was not found string string not found
            // otherwise if not found
            printf("Subtry not found \n");
        }
    }
    // free releases the memory area that was reserved for the string and substrings so that it can be reused in the next run
    free(str);
    free(sub);
    return 0; // exit analog
}

查看apache用户ENV变量要将变量添加到apache2 ENV，您需要使用putenv（“string”）;

你需要以这种方式添加aws cerdentials

getenv(); putenv('AWS_DEFAULT_REGION=' . $region); putenv('AWS_ACCESS_KEY_ID=' . $key); putenv('AWS_SECRET_ACCESS_KEY=' . $secret);e

当我尝试从php文件

运行aws cli时，只有这个解决方案适合我
