Question

我正在使用OKHTTP 3.x版本。我想发布多个参数，并希望在循环中添加参数。我知道在2.x版本中，我可以使用FormEncodingBuilder并在循环中添加params，然后从中创建一个请求体。但在3.x中，该课程已被删除。

这是我目前的代码：

RequestBody formBody = new FormBody.Builder()
            .add("Param1", value1)
            .add("Param2", value2)
            .build();
Request request = new Request.Builder()
            .url("url")
            .post(formBody)
            .build();

现在我想添加5个参数但是在一个循环中，即通过在循环中构建formbody来创建请求体。就像我上面写的那样，我知道如何在OKHTTP版本2.x中执行它，但我使用的是版本3.x.

感谢任何帮助或指导。

先谢谢

Answer 1

我是这样做的：

FormBody.Builder formBuilder = new FormBody.Builder()
        .add("key", "123");

// dynamically add more parameter like this:
formBuilder.add("phone", "000000");

RequestBody formBody = formBuilder.build();

Request request = new Request.Builder()
                .url("https://aaa.com")
                .post(formBody)
                .build();

进口

import okhttp3.OkHttpClient;
import okhttp3.FormBody;
import okhttp3.Request;
import okhttp3.RequestBody;

代码：

// HashMap with Params
HashMap<String, String> params = new HashMap<>();
params.put( "Param1", "A" );
params.put( "Param2", "B" );

// Initialize Builder (not RequestBody)
FormBody.Builder builder = new FormBody.Builder();

// Add Params to Builder
for ( Map.Entry<String, String> entry : params.entrySet() ) {
    builder.add( entry.getKey(), entry.getValue() );
}

// Create RequestBody
RequestBody formBody = builder.build();

// Create Request (same)
Request request = new Request.Builder()
        .url( "url" )
        .post( formBody )
        .build();

这是我的版本

public String postToServer(String url, List<Pair<String, String>> pairs) throws Exception {
    okhttp3.OkHttpClient client = new okhttp3.OkHttpClient();
    okhttp3.Request.Builder builder = new okhttp3.Request.Builder().url(url);

    if (pairs != null) {
        okhttp3.FormBody.Builder postData = new okhttp3.FormBody.Builder();
        for (Pair<String, String> pair : pairs) {
            postData.add(pair.first, pair.second);
        }
        builder.post(postData.build());
    }
    okhttp3.Request request = builder.build();
    okhttp3.Response response = client.newCall(request).execute();
    if (!response.isSuccessful()) {
        throw new IOException(response.message() + " " + response.toString());
    }
    return response.body().string();
}

我不确定，但你可以尝试这样的事情：

RequestBody formBody = new FormBody.Builder();
for(...;...;...) {
   formBody.add(...)
}
formBody.build();

你的其余代码似乎很好。希望它能工作:)！
